borrowing pronouns

[Rick Mc Callister]

>In addition, there are many Americans using "moi" who not only do not know
>French, but who never directly saw/heard Miss Piggy'.

>In addition, Casdtilian has "Vd/Usted" from Arabic "ustaeth" 'teacher; and

ustad/ustaz "sir, maestro" definitely looks like usted
but most other Spanish professors I run into
swear that it's from vuste/ a corruption of "vuesa/vuestra merced"

>Italian "Lei" is a calque of sorts on the latter.

I've been told that Mussolini encouraged Italians to use <voi>
by explaining that <Lei> was from Spanish <le>
and <Loro> was from French <leur>
and so, <voi> was the "national" form
Did he really say that?
